## Abstract Highly ordered hexagonal mesoporous silica materials (**JLU‐20**) with uniform pore sizes have been successfully synthesized at high temperature (150–220 °C) by using fluorocarbon–hydrocarbon surfactant mixtures. The fluorocarbon–hydrocarbon surfactant mixtures combine the advantages of
Carbon-13 chemical shifts are reported for tetralin, hydrophenanthrenes and hydropyrenes and their alkyl substituted derivatives. Mono-and di-plus tri-aromatic fractions of hydrogenated phenanthrene and pyrene were also examined by carbon-13 n.m.r. and, wherever possible, the components in them ide
