A novel colorimetric chemosensor PBIOSi has been designed and synthesized. The addition of F- to a THF solution of PBIOSi resulted in an obvious color change (from red to green) in a short time because of the specific cleavage of Si-O bond in P

In this report, three asymmetrical perylenediimide derivatives (PDI) substituted on the bay-position with para-alkylphenyl groups were synthesized, on which the substituted alkyl side chain was n-propyl (4-PP-PDI), n-hexyl (4-HP-PDI), or n-nonyl (4-NP-PDI

Amines play an important role in many physiological processes in living organisms. The present study explores the use of perylene diimide (PDI) and perylene monoimide (PMI) for the detection of common amines in solution. A systematic investigation using primary, secondary and tertiary amines as electron donors and perylene derivatives as electron acceptors is carried out in solution to understand the molecular interactions. Results from steady-state luminescence spectroscopy suggested that the PDI and PMI interact with the amine derivatives in the excited state, which led to photoinduced electron transfer and fluorescence quenching. Stern-Volmer plots were used to understand the quenching behavior of perylene derivatives in presence of various amines. The bimolecular rate constants of the dynamic quenching have been deduced for PDI, the values are in the range of 1.8?×?109?M?1s?1 for primary amines, 8?×?109?M?1s?1 for tertiary amines and 2.2?×?1010?M?1s?1 for aniline. Similar quenching rate constants for primary, secondary and tertiary amines were also observed for PMI. PDI showed higher selectivity for bulky hydrophobic amines over linear primary amines in solution. Such interactions could be investigated further to understand the response of perylene based sensors for amines.

The dyes (P-1 and P-2) of perylenebisimide (PBI) conjugated with 2-(2-hydroxyphenyl)benzothiazole (HBT) were prepared by Sonogashira coupling reaction. The new compounds have special photophysical properties, such as near infrared absorption/emission and large Stokes shift. The UV-vis absorption (range from 651 nm to 690 nm) and emission wavelength (range from 732 nm to 756 nm) of P-1 and P-2 extend to near infrared range. Importantly, they have much larger Stokes shifts (range from 73 nm to 105 nm) compared with the conventional PBI derivatives, such as 7 (from 19 nm to 65 nm) and 9 (from 81 nm to 86 nm). TD-DFT calculation was used to rationalize UV-vis absorption, emission and especially large Stokes shift from the theoretical point of view. We found geometry relaxation of P-1 and P-2 in the excited state is an important reason for the origin of large Stokes shift besides intramolecular electron transfer (ICT).
