A doubly alkylene bridged 6,13-diphenylpentacene and analogously bridged azapentacenes were prepared; they are persistent. The doubly bridged azapentacenes display superior photochemical, oxidative and thermal stabilities compared to azapentacenes protected by bis(TIPS-ethynyl)-substituents-clipping an azaacene into a large ring is a viable complement in stabilization. Hard domestic water has been reported to worsen atopic eczema (AE) and may contribute to its development in early life. To review the literature on the
