The diverse structures of molybdate anions significantly provide new opportunities to design various nanostructures MoOx-based organic–inorganic hybrids with prominent catalytic, electrochemical and photo/electrochromic properties. In this paper, the one-dimensional (1D) growth originating from anisotropic is successfully introduced prepare a series hybrid nanowires Mo3O10(C6H8N)2·2H2O (anilinium trimolybdate), Mo3O10(C2H10N2) (ethylenediamine trimolybdate) Mo3O10(C5H6N)2·H2O (pyridium trimolybdate). Taking for example, 1D proved be associated chain-like structure Mo3O102− by both experiments quantum chemical calculations. Meanwhile, synthesis parameters, e.g., reacting time, pH conditions feeding ratio, show obvious influences on product morphologies based different anions, further validating mechanism. More importantly, as-obtained MoOx/amine remarkably exhibit tunable photochromic properties depending their composites, which presents potential well-tailored functional optical nanodevices.
