Synthesis of Liquid Crystalline 3H-Naphtho［2,1-b］Pyrans and Studies on Their Photochromic Characteristic

工程科学与技术, 2007
:N,N,N-trimethyloctadecan-1-aminium chloride was used to prepare 6-dodecylnaphthen-2-ol. And three novel 3H-naphtho［2,1-b］pyrans with long chain substituents were synthesized by the condensation of 6-n-dodecylnaphthen-2-ol with prop-2-yn-1-ols, which ...
