Photochemistry of N, Ń-ditridecyl-3,4:9,10-perylenetetracarboxylic diimide in chloromethane solvents

The spectral behaviour, lifetime and fluorescence quantum yield of N,N-ditridecyl-3,4:9,10-perylenetetracarboxylic diimide (DTPD) have been measured in chloromethane solvents, such as methylene chloride, chloroform and carbon tetrachloride. The excitation energy transfer to DTPD has been studied to...

Description
Summary:The spectral behaviour, lifetime and fluorescence quantum yield of N,N-ditridecyl-3,4:9,10-perylenetetracarboxylic diimide (DTPD) have been measured in chloromethane solvents, such as methylene chloride, chloroform and carbon tetrachloride. The excitation energy transfer to DTPD has been studied to improve the laser emission of DTPD. The value of energy transfer rate constant ( K ET) and critical transfer distance ( R 0) indicate a Förster type energy transfer mechanism. The photodecomposition of DTPD in chloromethane solvents has been also studied.
