This work reports the synthesis of a new fluorescent sensor type open chain bischromophoric, with ether and amino groups as receiver units and naphthalene as indicator unit (L1), and the synthesis of M1 by methodology of synthesis organic phase solid (SOFS) supported in Merrifield resin, which has a similar structure to L1. For both ligands complexation studies by fluorescence technique with alkali metals (Li+, Na+ and K+) were carried out.  Coordination studies with M1 showed increased fluorescence response in presence of Li+ and Na+ and no response in presence of K+, whereas L1 present an increased fluorescence response for Li+, an increase of 1.2 times in the intensity of monomer emission band and 6 times in the excimer emission band; Na+ and K+ did not affect the fluorescence of L1.
