## Abstract Possibilities to synthesize substituted oligo[(hydroxy‐1,3‐phenylene)methylene]s containing hydroxynitrophenylene and alkylhydroxyphenylene units are discussed. The only successful way to introduce the hydroxynitrophenylene unit consists in the condensation of chloromethylated nitrophen
## Abstract The structures of two homologous series of oligo[(2‐hydroxy‐1,3‐phenylene)methylene]s completely esterified with methacrylic acid, were spectroscopically analysed. The molar decadal absorption coefficients of ultraviolet absorption maxima of the two homologous series confirm Hunter's re
## Abstract The stepwise syntheses of cyclo{quater[(5‐alkyl‐2‐hydroxy‐1,3‐phenylene)methylene]}s (**5**) are described and compared with a one‐flask reaction procedure. The structures of the cyclic compounds **5** are analytically confirmed and their properties were compared with those of linear ph
