Today we are finishing the story on Photovoltaics (check last week's slides).
If we have time left we will make a start with Organic Light-EmittingDiodes

After the two more biological-related topics, back to the chemistry: photoreactions can we predict them? For this we need to make correlation diagrams.
We turn to Chapter 4.9 of Klan&Wirz

For a more thorough read turn to Chapter 6 of the Photochemistry 'bible'by N. Turro
 

Extra slides added for today

Slides for Monday 13-10-2014

Today we kick off the nature's photochemical masterpiece: photosynthesis. Combining both energytransfer and electrontransfer processes. Before studying this, maybe first look at the links (youtube movies in the next post, and ch9.2 of Björns Photobiology

Here are the slides I am going to use:

Thursday 9 October

Today we finish the story of vision, by looking at color blindness (integrated into monday's slides here)
Also see the post below with interesting and cool links on color and vision


As we now started to see some first actual photochemistry it becomes apparent we need to know some more about reactive pathways in the excited state (prepare by reading ch. 2.3 of Klan and Wirz)

Monday Oct 6 Photochemistry of vision

Photochemistry of Vision
Now well aware about the theories behind vision and colour, let's go back to the photochemistry. How do photons 'trigger' signals in rods and cones.

And all was light..... (Thursday 2 Oct)

Moving into the daily reality of photochemistry now. We will see many natural and artificial processes in the upcoming weeks and we dive a bit deeper into the photophysical mechanisms underlying these day to day events. We start of with colour and vision. Thursday a general intro, next week looking at the photochemistry and photobiology of rhodopsins that make this all possible.

As an intro, read Klan&Wirtz Ch 1.3

Changed the timing a bit

as we have progressed the timing of the subject has shifted a bit. I have posted an updates course schedule (with chapter references up to now)

Thursday 18/9/2014

Today we will finish the story on Spectroscopy (slides last week)
I will also introduce potential energy reaction surfaces that give us tools to understand better actual photochemical ractions (involving molecular changes)

Preparing for Thursday 11 sept 2014 lecture

Today we hope to finish our survey of spectroscopic techniques.
Please continue to refer to the material as presented for the monday lecture (slides, bookschapters).
The halfway exam is coming soon, so you should be up to date with your reading

Friday 5 September 2014

Slides for Monday 8 September

We will now talk about the techniques to measure all the phenomena we discussed in the past few weeks: spectroscopic techniques.
In the books: Klan&Wirz Chapter 3 (not in all detail)

Valeur: Chapter 6

Thursday 4 Spetember 2014

We continue to use the slides posted on Monday.
Continuing the story on electron transfer

Friday 29 August 2014

Slides for Monday 1 Sept 2014

Up to now we have purely looked at unimolecular photophysical processes after photoexcitation. It is time we bring in some photochemistry by looking at interactions between the excited molecule and other molecules. The slides are here:
https://drive.google.com/file/d/0B_AdLmUQhTCYN2l1T2tZY1MzZXc/edit?usp=sharing
In the textbooks this is dealt with in the following paragraphs:
Valeur: CH4.1-4.4 (selected parts) and CH9
Klan&Wirz: CH2.2. and CH5.1-5.3

Monday 25 August 2014

Thursday 28-8-2014

Today we continue to use the slides I posted for monday.
More on fluorscence, phosphorescence, lfetimes and quantum yields.
So in Klan and wirz we finish ch2.1
In Valeur this is mainly in Ch. 3.1 and 3.2

Friday 22 August 2014

Slides for Monday 25-8-2014

We will continue our deeper understanding of the photophysical processes.
Especially looking at Frank Condon factors, luminescence (and some empirical rules that apply) and quantum yields.
In Klan&Wirz this is mostly described in Ch 2.1.3 and Ch 2.1.5-2.1.9
In Valeur the same is explained in 2.4 and 3.1.
The slides we will use:
https://drive.google.com/file/d/0B_AdLmUQhTCYczNHaHMyNWNJdlU/edit?usp=sharing

(slide 27 onwards)

Tuesday 19 August 2014

Thursday 21-8-2014

We will be mainly focusing on Klan and Wirz 2.1..1, 2.1.2, 2.1.3 and 2.1.4
You can also turn to Ch. 2 of Valeur

We will do some exercises as well.
Here are the slides (probably thursday we run up and till slide 33):

We continue using the slides from the previous post.

 To properly prepare, read Klán&Wirz Ch2.1

It is a good and fast introduction into the conventions around the Jablonski Diagram

Wednesday 13 August 2014

Thursday 14-8: Introduction

We are really kicking off now. You will find the slides below:

 1. introduction
1. introduction

In the textbook of Klan and Wirz (Photochemistry of Organic Compounds) this is basically Chapter 1.1, 1.2, 1.4 (except for special topic 1.1).  
1.3 will also be treated seperately later when we also deal with colourvision
