title: Exciplex formation between pyrene and guanine in highly polar solvents.
abstract: Guanine derivatives connected to pyrene with methylene spacers exhibited exciplex emission in highly polar solvents such as N,N-dimethylformamide, acetonitrile, and water. The result will open up a novel approach to synthesis of fluorescent nucleic bases.
