摘要：

The photochemical behaviour of trans-2-styrylpyridine in various cation-exchanged faujasite zeolites has been investigated. At a lower loading level, trans-cis isomerization is the only process. When the loading level is increased, in addition to isomerization, significant amounts of dimerization and cyclization products are also observed with the products distribution depending on the free volume available inside the cage. Acidic zeolites such as HY and MgY are found to catalyse the thermal reaction of 2-styrylpyridine. (C) 2000 Elsevier Science S.A. All rights reserved.
