We have synthesized derivatives of pyropheophorbide-a with electron donor and acceptor groups which localize in lipid membranes and can be used for multi-photon imaging via second harmonic generation and two-photon excited fluorescence.

DFT B3LYP method was employed to calculate the second-order nonlinear optical (NLO) responses of the derivatives of disubstituted seven-vertex cobaltacarborane metallocenyl. The results show that cobaltacarborane metallocenyl plays a pushing/pulling role and a bridge role to transfer electron in these molecules. The five-membered ring of cyclopentadiene is more beneficial to increase second-order NLO response than the five-membered ring composed of two C atoms and three B atoms in cobaltacarborane. Moreover, the second-order NLO response is more powerful when one substituent containing electron donor group and one substituent containing electron acceptor group are located at meta position. Accordingly, among the nine models, model c2 is the optimum model with largest value of βtot. The calculation results also show that cobaltacarborane metallocenyl and ferrocene parts play the same roles to increase second-order NLO response. Thus, cobaltacarborane metallocenyl can be a promising second-order NLO material.

Various triethylphosphine coordinated gold(1) mercaptides of formula Et3PAuSR (R = Me, Et, Pr, Bu, Bu1, Ph, CH2Ph, β-C10H7, and CH2CH(NH2)C02H), and related sulphur derivatives of formula Et3PAuY (Y = SCN, SC(S)Net2, SC(S)OEt, and SC(NH2)NH2+Br-) have been prepared. Under appropriate conditions, displacement of the sulphur group from the gold atom is observed, either by another sulphur nucleophile, e.g. Et3PAuSR + Et2NCSS- → Et3PAuSC(S)Net2 + RS-, or by a. nucleophile such as Cl-, Br-, I-, NO3-, or CN-.
