“…In addition, two new absorption bands appeared at 1325 and 1155 cm À1 , which were ascribed to the asymmetric and symmetric stretching frequencies of S¼O. [32] These results revealed that the modified nanoHAP were functionalized by -SO 3 H groups successfully. XRD measurements were used to identify the crystalline structure of HAP@AEPH 2 and HAP@AEPH 2 -SO 3 H. As shown in Fig.…”

“…or Ln 3? ) exhibit much higher fluorescence [25]. In 8-hydroxyquinoline metal complexes (such as Alq3), the lowest electronic transitions are p to p* transitions in the quinolate rings, involving partial charge transfer from the phenoxide ring (ring that has OH group) to the pyridyl ring (with N in its ring).…”

“…Using hybrid materials synthesized by conventional solgel method as a host for Alq3 is reported in literature for different reasons such as color tuning or morphological control [24][25][26]. In all these and similar works hybrid network act as a host for Alq3 with no chemical bonding between them.…”

“…Then attraction of other scientists to this materials caused discovery of other types of nanoporous materials such as SBA-15 (Zhao et al, 1998), LUS-1 (Bonneviot et al, 2003), FSM-16 (Inagaki et al, 1993), KIT-1 (Ryoo et al, 1996), MSU (Bagshaw et al, 1995), and HSM (Tanev & Pinnavaia, 1995)which were synthesized within highly acidic to strongly basic pH range using cationic, anionic, neutral and nonionic structure directing agents. Among these materials, MCM-41, LUS-1 and SBA-15 are most studied ones in our previous researches such as studies on metal modification Béland et al, 1998), pre-concentration of metals (Ganjali et al, 2006;Javanbakht et al, 2009b;Javanbakht et al, 2010), modification with 8-hydroxyquinoline (Badiei et al, 2011b;Badiei et al, 2011a), carbon paste electrodes (Ganjali et al, 2010;Javanbakht et al, 2007a;Javanbakht et al, 2007b;Javanbakht et al, 2009a), solid phase micro extraction (Hashemi et al, 2009) and hydroxylation catalysts (Arab et al). Therefore, these materials are the major subject in the coming discussions about catalytic synthesis of CNTs.…”
