TLDR
The effect of electron-donor (piperidino) and electron-acceptor (cyano) groups on the absorption maxima of some diketo-pyrrolo-polypyrroles in DMSO solution was investigated both experimentally and theoretically as discussed by the authors.About:

Colorimetric and Ratiometric Fluorescent Chemosensor Based on Diketopyrrolopyrrole for Selective Detection of Thiols: An Experimental and Theoretical Study
Ling Deng,Wenting Wu,Huimin Guo,Jianzhang Zhao,Shaomin Ji,Xin Zhang,Xiaolin Yuan,Chunlei Zhang +7 more
TL;DR: A colorimetric and ratiometric fluorescent thiol probe was devised with diketopyrrolopyrrole (DPP) fluorophore and it was demonstrated that besides the expected Michael addition of thiols to the C═C bonds, the CN groups of the malonitrile moieties also react with thiolS to form 4,5-dihydrothiazole structure.

Diketo-Pyrrolo-Pyrrole Dyes as New Colorimetric and Fluorescent pH Indicators for Optical Carbon Dioxide Sensors
TL;DR: The dynamic range of the sensors based on the new indicators is significantly different (0-10 kPa and 1-100 kPa CO2) that enables a broad variety of applications and represents a new class of colorimetric and fluorescent pH indicators for optical carbon dioxide sensors.

Rational molecular design towards Vis/NIR absorption and fluorescence by using pyrrolopyrrole aza-BODIPY and its highly conjugated structures for organic photovoltaics.
TL;DR: To control the absorption and fluorescence of PPAB, particularly in the near-infrared (NIR) region, further molecular design was performed using DFT calculations, which results in the postulation that the HOMO-LUMO gap of P PAB is perturbed by the heteroaromatic moieties and the aryl-substituents.
