Accurate and tunable: The title compounds can detect reactiveoxygenspecies (ROS) in cellculture, tissue explants, and for the first time in vivo. The hydrocyanines are synthesized by reduction of the cyanine dyes with NaBH4. They can accurately detect nanomolar levels of ROS, have excellent stability against autoxidation, and have tunable emission wavelengths in the range 560–830 nm.

A polymer having a polymerizable group and an alkyleneoxy groups on side chains thereof, and a polymerizable composition containing the polymer. The polymerizable composition preferably contains a polymerizable compound and a polymerization initiator. Also provided is a planographic printing plate precursor having a polymerizable layer on a hydrophilic support, the polymerizable layer containing a polymer having a polymerizable on a side chain thereof. The planographic printing plate precursor can form an image without being subjected to an alkali development. An undercoat layer containing a specific copolymer may be provided between the support and the photopolymerizable layer.
