Abstract

Novel soluble polyimides containing perylene units have been synthesized. The polymers were prepared in a one‐step polycondensation reaction from 1,6,7,12‐tetrakis(4‐tert‐butylphenoxy)‐3,4:9,10‐perylenedianhydride and aliphatic and aromatic diamines. The amorphous polyimides have a very good solubility in a wide range of organic solvents and exhibit thermal stability up to 350°C. The polymers consist of 10 to 30 monomer units and show a narrow molecular weight distribution. The dark red materials can be used as polymeric dyes (absorption wavelength: λ~max~ = 590–610 nm) and exhibit fluorescence near 620 nm.

Aliphatic polyimides containing adamantyl units (APIs) were prepared by the poly(addition/condensation) of a dianhydride bicyclo[2.2.2]octane-2,3,5,6-tetracarboxylic 2,3 : 5,6-dianhydride with a rigid diamine, 1,3-diaminoadamantane or 3,3Јdiamino-1,1Ј-biadamantyl, and a flexible diamine, 4,4Ј-methyl
