The photoreactions of 1,4-diphenyl-1,3-butadienes (DPB) fused with a bicyclo[2.2.1]heptano ring under direct irradiation were examined in solution at room temperature and in organic glass at liquid nitrogen temperature. Photocyclization yielding a phenylnaphthalene compound was shown to be preceded by facile E,E to E,Z photoisomerization. The reverse E,Z to(More)
13. ABSTRACT (Maximum 200 words) Diamond films are impbrtant for radiation tolerant devices. However, fabrication of single crystal films has proven to be much more difficult than polycrystalline deposits. A novel deposition process is proposed which can be used to deposit diamond on a seed crystal. The technique permits patterned deposits in islands and(More)
