	abstract = {<p>We report here a smart functional low molecular weight gelator (LMWG) L, containing an unusual metal ion coordination site, i.e. {\textquoteleft}{\textquoteleft}half-crown/two carbonyl{\textquoteright}{\textquoteright}. The gelator L shows excellent gelation behavior with typical fibrillar morphology in acetonitrile, methanol and ethanol media. Upon Ca2+ ion binding with its {\textquoteleft}{\textquoteleft}half-crown/two carbonyl{\textquoteright}{\textquoteright} coordination site, the acetonitrile gel of L exhibits a fiber to nanosphere morphology transformation along with a gel-to-sol phase transition as confirmed by microscopic investigation and by direct naked eye visualization, respectively. The mechanism involved in this morphology transformation and gel-to-sol phase transition process was studied thoroughly with the help of computational calculations and various spectroscopic experiments and discussed.</p>},
