The Front Cover shows the methodology for the synthesis of diversified “Y‐enyene” BODIPY derivatives, obtained through the Pd‐catalyzed Sonogashira coupling reaction of gem ‐dibromo BODIPY and alkyne derivatives. The coupling products possess interesting spectral properties (UV/Vis and fluorescence), providing the potential to develop fluorescence probes and photosensitizers for photodynamic therapy (PDT). Protonation of dimethylaminphenyl substituted BODIPYs induces changes in their spectral properties, from fluorescence off‐to‐on. Their strong electrochromic properties render these derivatives most suitable for the construction of multifunctional electro‐ and photo‐chemical molecular switches.
