Protochlorophyllide a: A Comprehensive Photophysical Picture
Benjamin Dietzek,Stefanie Tschierlei,Gudrun Hermann,Arkady Yartsev,Torbjörn Pascher,Villy Sundström,Michael Schmitt,Juergen Popp +7 more
TL;DR: Pump-probe spectroscopy reveals a previously concealed photointermediate, whose formation on a nanosecond timescale matches the overall fluorescence decay and is assigned to a triplet state of protochlorophyllide a.

The Excited‐State Chemistry of Phycocyanobilin: A Semiempirical Study
TL;DR: It is shown by quantum chemical calculations that the basicity of phycocyanobilin is much higher in the excited than in the ground state, with a decrease in the exciting-state pK(B)* of approximately 9.5 units.

Excited-State Processes in Phycocyanobilin Studied by Femtosecond Spectroscopy†
TL;DR: In this article, the light-induced photoprocesses of phycocyanobilin were studied by femtosecond spectroscopy after excitation with 100 fs pulses at 610 nm.

Femtosecond time-resolved spectroscopy on biological photoreceptor chromophores
TL;DR: In this paper, the femtosecond time-resolved spectroscopy (transient absorption, transient-grating and fluorescence spectrograms) was used to study the photophysics and photochemistry of the two very important biological photoreceptor chromophores phycocyanobilin (PCB) and protochlorophyllide a (PChla).

Excited-state processes in protochlorophyllide a – a femtosecond time-resolved absorption study
Benjamin Dietzek,R. Maksimenka,T. Siebert,Eckhard Birckner,Wolfgang Kiefer,Juergen Popp,Gudrun Hermann,Michael Schmitt +7 more
TL;DR: In this article, the excited-state dynamics of protochlorophyllide a, a porphyrine-like compound and precursor of the chlorophyll biosynthesis, was studied by femtosecond absorption spectroscopy.
