Chemical structure of 4-phenylpiperidine. Phenylpiperidines are chemical compounds with a phenyl moiety directly attached to piperidine. Of particular interest are a variety of derivatives of 4-phenylpiperidine, which have pharmacological effects including morphine-like activity [1] or other central nervous system effects.
Pyridine and poly(4-vinyl) pyridine have been shown to form conducting molecular wires with remarkable polyenimine structure on UV irradiation, a process which accounts for at least some of the visible light absorption by aged pyridine samples. These wires have been theoretically predicted to be both highly efficient electron donors and ...
