Today I am chairing a session on charge transport at an I2CAM Exploratory Workshop, Complex Interactions and Mechanisms in Organic Photovolt...

Physicists say the details don't matter. Chemists say they do. Biologists say the details are a matter of life and death. If you make a ...

Today I am giving the "cake meeting" talk. I will mostly go through some key ideas about excited states of organic molecules, that...

Thinking more about my earlier post, Key questions about organometallic materials for LEDs , I realised there is a subtlety that is sometime...

The figure below, taken from a JACS paper , is a possible schematic for photo-physics of the excited states of Ru(bpy)3 which is a model com...

As discussed in many other posts on this blog, organometallic complexes, exhibit rich photophysics and find application in a new generation ...

Organometallic complexes are a key functional component of many organic LED's and photovoltaic cells. Understanding their excited state ...

Previously I have written posts about the important issue of understanding (and enhancing) the charge mobility of molecular materials. Key...

Next month I am going to India to speak at a School and Conference on “Emergent Properties and Novel Behavior at the Nanoscale” organised b...

Previously, I asked is organic semiconductors a misnomer ? One needs to be very careful about trying to apply the same concepts from inorgan...

As a physicist trying to understand what makes a good organic LED material it is easy to get lost in all the chemical details. Today I came ...
