✦ Synopsis

Ace-nd time-resolved enussion studies of a series of rnoleculec Eirniaining an electron donor-aocP_ptor pair intereon-ne~kd by a senes of npd non-coqugated bridges reveal the occurrence of very fxl photoinduced inkunolecular eleclron nansfer_ The length of the bndgewas varied 10 provide donor-aoxptor czmrc-lo-ozntre separations ranging frpm 8.1 LO 13 3 A (edge-tcxdge 5 lo 10.2 A). Al ccntre-to-cenue separations up LO 10.7 A Lhe rate of photoinduced eleclron transfer exceeded 5 x 10" s-' (7 -z 20 ps); at Lhe largesl separation. 13.3 A. the rale was 1-47X 10" s-' (T = 68 ps).

## Abstract Helical peptides of 8mer, 16mer, and 24mer carrying a disulfide group at the __N__‐terminal and a ferrocene moiety at the __C__‐terminal were synthesized, and they were self‐assembled on gold by a sulfur–gold linkage. Infrared reflection–absorption spectroscopy and ellipsometry confirme

In continuation of previous syntheses of benzene-, These donor-acceptor systems are of interest since, with regard to electron-transfer rates, they complete the series of naphthalene-, and anthracene-spacered porphyrin-quinone cyclophanes 1, 2, and 4, biphenylene-spacered porphyrin-1, 2, and 4.
