We demonstrate for the first time the utility of time-resolved visible pump/mid-infrared (IR) probe spectroscopy to interrogate directly, and provide unique infomation regarding, conformationally dependent photoinduced ET dynamics and the subsequent structural evolution of the resulting charge-separated (CS) state. Exemplary

Nanowires from deposition of pyromellitic diimide (PMDI) from the gas phase and their unique excitation-wavelength-dependent photoluminescence were demonstrated. The luminescence peaks of the PMDI nanowires red-shifted as the excitation wavelength increased. The relationship between the luminescence peak and the excitation

This paper reports the electroscopic and electrochemical properties of [2 + 2] pyromellitic diimide-based cyclophane 1 as well as acyclic N,N'-bis(2-methoxybenzyl)pyromellitic diimide 2 and the clathrate compounds formed by 1. Compound 1 was synthesized by direct cyclocondensation. Its structure was

The hydroxo-complexes [Ni(2)(mcN(3))(2)(mu-OH)](2)(PF(6))(2)] [mcN(3) = 2,4,4-trimethyl-1,5,9-triazacyclododec-1-ene (Me(3)-mcN(3)) or 2,4,4,9-tetramethyl-1,5,9-triazacyclododec-1-ene (Me(4)-mcN(3))] react with imides (Him) in 1 : 2 (succinimide, glutarimide, saccharine and 1,8-naphthalimide) or 1 : 1 (pyromellitic diimide) molar ratio, leading to the formation of the imidate complexes: [Ni(mcN(3))(H(2)O)(Im)](+)
Complex formation of pyromellitic diimide derivatives with beta-cyclodextrin and anthracene-appended beta-cyclodextrin was studied with use of induced circular dichroism and 1H NMR spectroscopies. It is revealed that pyromellitic diimides form rim-binding type complexes with beta-CD and in these complexes the
