TLDR
The synthesis and study of a rigid "coplanar" noncovalent electron-transfer model system that juxtaposes a novel donor and acceptor via a three-point hydrogen bonding interaction is described.Abstract:
Described in this paper is the synthesis and study of a rigid “coplanar” noncovalent electron-transfer model system. This putative noncovalent complex juxtaposes a novel donor (chlorin) and acceptor (naphthalene diimide) via a three-point hydrogen bonding interaction (CDCl3, Ka = 364 ± 47 M-1). It was studied by steady state fluorescence, time-resolved luminescence, and transient absorption methods. The results of the studies are consistent with (1) forward intraensemble electron transfer (ET) taking place rapidly following photoexcitation of the chlorin donor at 575 nm (kET = 7.6 × 108 s-1; ΔGcs ∼ −457 mV; Φ = 0.91) and (2) back electron transfer occurring even more rapidly.read more

Hydrogen bond directed self-assembly of core-substituted naphthalene bisimides with melamines in solution and at the graphite interface
TL;DR: A series of red and blue highly fluorescent core-substituted naphthalene bisimide dyes has been synthesized and they have been investigated as supramolecular building blocks but little evidence for heterocomplexes between the two complementary building blocks could be obtained.

Synthesis and photoinduced intramolecular processes of light-harvesting silicon phthalocyanine-naphthalenediimide-fullerene connected systems.
TL;DR: Photoinduced intramolecular processes of a newly synthesized pentad composed of silicon phthalocyanine (SiPc) that is connected with two units of naphthalenediimide (NDI) and fullerene C(60) to form SiPc-(NDI)(2)-(C(60))(2) have been studied and the results are compared with the reference compounds.

Nature of biological electron transfer
TL;DR: Powerful first-order analysis of intraprotein electron transfer is developed from electron-transfer measurements both in biological and in chemical systems, finding selection of distance, free energy and reorganization energy are sufficient to define rate and directional specificity of biological electron transfer.
