Chemical vapordepositionpolymerization is used to prepare submicron thin films of poly(p-xylylenes) with distinct chemical and optical properties. The polymers are prepared from 13 different [2.2]paracyclophanes with variable degrees of substitution and functionalities including hydroxy, methoxy, amino, triflate, or trifluoroacetyl groups. The chemical composition of the poly(p-xylylenes) is in good

By cyclopropanation of tetramethyl[2.2]paracyclophane 9 the tetramethylene adduct 10 has been prepared. This hydrocarbon is the first stablecis-bis-σ-homobenzene for which a structure has been determined by X-ray diffraction.
通过四甲基[2.2]对环芳烷9的环丙烷化,已经制备了四亚甲基加合物10。这种烃是第一个稳定的顺式双σ-均苯,其结构已通过 X 射线衍射确定。
Syntheses of various symmetrical naphthalenophanes and anthracenophanes via a Diels–Alder reaction between syn-[2.2](5,8)phthalazinophane derivatives and some selected dienophiles as well as the synthesis of other symmetrical heterophanes

The syntheses of various classes of unreported naphthalenophanes, anthracenophanes and heterophanes are herein reported. The key to their successful preparation depends on the synthesis of syn-4,7,14,17-tetra(phenyl and chloro)-[2.2](5,8)phthalazinophanes as well as syn-4,5,6,7,14,15,16,17-octahydro[2.2](5,8)phthalazinophane- 4,7,14,17-tetraone and 4,5,12,13-tetrakis(methoxycarbonyl)-[2.2]paracyclophane
