Recent research trends on the photophysical properties of transition metal complexes under rigid environments are overviewed. Since the transition metal complexes are often introduced into rigid environments in photochemical applications/devices such as organic light-emitting diodes (OLEDs) and dye-sensitized solar cells (DSSCs), the rigid medium effects on the excited-state characteristics of the complexes are still worth studying. Crystalline solids, frozen glasses and polymer matrices are picked up as examples of rigid environments. Under these conditions, the metal complexes show characteristic photophysical properties which differ from those in fluid solution owing to the rigidity of the surrounding environments.
