Photocrosslinkable molecules are also discussed which form insoluble films on illumination with ultra- violet light. This approach combines the ease of  deposition of small molecules with the robustness  and stability of polymers, allowing simple  fabrication of multi-layer EL devices and  photopatterning. A range of conjugated low molar- mass molecules are considered, containing the  anthracene, perylene and fluorene cores. An acrylate  and several diene photopolymerisable derivatives of  the fluorenes undergo photocrosslinking. A diene  shows no significant degradation for an optimal  exposure and a doped photo-alignment layer is used  for the first time to obtain polarised EL with ratio  11:1 and a brightness of 80 cdm-2 from the  crosslinked diene. The insoluble crosslinked network  allows the spin-coating deposition of an  electrontransporting over-layer, resulting in  increased brightness.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838334745\"\u003e\u003ch3\u003eEase of deposition of small molecules with the stability of polymers allows multi-layer  photopatterned EL devices\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838334745","offer_id":39498938286173,"sku":"9783838334745","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/cfaa6d20-2263-4732-b53c-fb716dc0d9e7.jpg?v=1774759555","url":"https:\/\/shop.autorenwelt.de\/products\/liquid-crystalline-networks-for-electroluminescent-displays-von-adam-contoret","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
