Abstract
Disclosed are fluorescent compounds useful as intracellular pH probes. In particular, the invention teaches a two-photon absorbing, water soluble, fluorescent compound, a fluorene derivative, which is effective as a near-neutral pH indicator and particularly as an intracellular probe. A method for chemical synthesis of the claimed compounds is provided.
