AB  - The microscopic orientation and position of photoactive molecules is crucial to 
      the operation of optoelectronic devices such as OLEDs and solar cells. Here, we 
      introduce a shape-persistent macrocyclic molecule as an excellent fluorescent 
      probe to simply measure (i) its orientation by rotating the excitation 
      polarization and recording the strength of modulation in photoluminescence (PL) 
      and (ii) its position in a film by analyzing the overall PL brightness at the 
      molecular level. The unique shape, the absorption and the fluorescence properties 
      of this probe yield information on molecular orientation and position. We control 
      orientation and positioning of the probe in a polymer film by solvent vapor 
      annealing (SVA). During the SVA process the molecules accumulate at the 
      polymer/air interface, where they adopt a flat orientation, much like water 
      lilies on the surface of a pond. The results are potentially significant for OLED 
      fabrication and single-molecule spectroscopy (SMS) in general.
