Abstract

On the basis of the CLE. (1931) colour metric an expression is developed for the colour co‐ordinates and luminosity of a given light source seen at night through an atmosphere of known optical properties. This is applied to an observation on a mercury vapour lamp in a highly selective haze of the type sometimes called “blue fog”.

## Abstract **Summary:** A new poly(fluorene‐__co__‐carbazole) (PFC‐1) with a large substituent group (ADN, a naphthalene‐anthracene derivative moiety) at the 9‐position of carbazole was synthesized. Compared with poly(fluorene‐__co__‐carbazole)s that have an alkyl substituent group at the 9‐positi
