cze	Nové dibenzothiofenové chromofory s postranním barbiturovým akceptorem	Byly připraveny nové chromofory na bázi 2,8-disubstituovaného dibenzothiofenu nebo dibenzothiofen-S,S-dioxidu. Spojení centrální jednotky s postranním barbiturovým akceptorem prostřednictvím pi-konjugované spojky zajistilo modulování vlastností chromoforů. Byly syntetizovány čtyři finální chromofory a šest meziproduktů, látky byly plně charakterizovány. Byly u nich studovány vztahy mezi strukturou a vlastnostmi.	dbenzo[b,d]thiofen; N,N '-Dibutylbarbiturová kyselina; chromofor; pi-konjugovaný systém; Knoevenagelova kondenzace
eng	Novel dibenzothiophene chromophores with peripheral barbituric acceptors	A series of novel chromophores based on central 2,8-disubstituted dibenzothiophene (DBT) or dibenzothiophene-S,S-dioxide (DBTO) has been designed and prepared. The interconnection of DBT(O) central scaffold with two peripheral barbituric acceptors via various pi-spacer allowed significant property tuning of target chromophores. Four new final chromophores and six DBT(O)-intermediates have been successfully synthesized and fully characterized. Experimental and calculated data showed that the fundamental properties are affected by the chromophore A-pi-D-pi-A or A-pi-A-pi-A arrangement (DBT vs. DBTO) and the pi-linker (ethenylene vs. ethynylene). Thorough structure-property relationships have been elucidated and discussed in detail.
