The present work deals with a new one-dimensional (1D) organic–inorganic hybrid material, namely (C9H10N2)PbCl4 (abbreviated as AQPbCl4). Its crystal structure is built up from the infinite 1D chain of edge-sharing PbCl6 octahedra surrounded by 3-aminoquinoline (abbreviated as AQ) organic molecules. Contrary to the most organic–inorganic hybrid materials, where the organic moieties act as barriers and the inorganic parts play the role of quantum wells, both inorganic and organic parts in AQPbCl4 are optically active, giving rise to optical properties involving the competition and the interaction of two organic and inorganic emitting entities. Under UV excitation, this hybrid compound shows a strong yellowish white-light emission that can be seen even with the naked eye and at room temperature. The photoluminescence spectrum is composed of a strong and broad yellow band at 538 nm associated with π–π* transition localized within the AQ organic molecule and a less intense band in the UV region at 340 nm asso...
