We have designed and synthesized a fluorescent, self-assembled molecular square containing a highly fluorescent well known flurophore boradiazaindacene (BODIPY) dye. Pt(II) complexes were used to hold together BODIPY derivatives and give the right angle to form the square structure. Usage of BODIPY fluorophore is very important on such structures because its variety of superior properties. BODIPY is a well studied fluorophore in our group and it is known that this self assembled square can be easily modified to any area of use it is needed.
